I keep seeing posts of "how does a pipe work?" "how do port timings work" "how does *** work". There are some really good readings out there. Randy at WATCON has some of the best books on the stuff but very few buy them and read. Yes, there is stuff on the web but a good book you can keep looking at, not hurt your eyes and ponder on again and again. I enjoy it when I get to share engine specs with someone who has different specs and got similar results or better. Sorry for the rant but damn, get a book! Then ask whats the result? Not how does it work? Will someone tell me so I don't have to read. I could, but you don't know enough to understand the answer. Ok, I feel better now!
